Hypodermic projectile

ABSTRACT

A cartridge is composed of a casing which houses a detonating charge and of a bullet body inserted thereinto having an outer hollow portion made of a ductile material such as plastic, zinc, lead, rubber or the like to be compressed upon reaching a target. An upstanding hypodermic needle and a hypodermic medium are arranged within said hollow bullet body and upon impact upon a target the needle penetrates through the wall thereof into the target and carries hypodermic medium thereinto.

Smolka ABSTRACT: A cartridge is composed of a casing which houses a detonating charge and of a bullet body inserted thereinto having an outer hollow portion made of a ductile material such as plastic, zinc, lead, rubber or the like to be compressed upon reaching a target. An upstanding hypodermic needle and a hypodermic medium are arranged within said hollow bullet body and upon impact upon a target the needle penetrates through the wall thereof into the target and carries hypodermic medium thereinto.

HYPODERMIC PROJECTILE My invention pertains to improvements in cartridges used in paralyzing men or animals and its main object is to project such cartridges from a gun or the like forcibly discharging therefrom a hypodermic fluid into the target upon impact.

Other objects of my invention will be more fully understood from the following specification when read with the accompanying drawing illustrating three embodiments.

FIG. 1 shows a longitudinal sectional view of a cartridge composed of a shell or casing containing a propellant and of my new bullet inserted thereinto;

FIGS. 2 and 3 show longitudinal sectional views of the bullet in two succeeding stages after firing;

FIG. 4 shows a longitudinal sectional view of another embodiment of the cartridge;

FIG. 5 is a longitudinal sectional view of the bullet thereof after impact upon the target;

H6. 6 is a longitudinal sectional view of still another embodiment of the cartridge;

FIG. 7 is a longitudinal sectional view of the bullet upon impacting the target, and

FIG. 8 is a cross section along line 8-8 in FIG. 7.

The same reference numerals are used in all figures to indicate the at least substantially same parts of the cartridge.

The embodiment shown in FIGS. 1 to 3 comprises a usual cartridge shell or casing 10 filled with an appropriate detonating means 12 and a bullet ll seated in said shell. The bullet 11 is a closed hollow body which at least in its outer part 11a is made of a compressibly deformable ductile material such as plastic, zinc, lead, rubber or the like. At the base of the hollow bullet 11 is a deformable, for example plastic sack or similar container 13 which is filled with an anesthetic and is communieatingly topped by the baseplate 15 of an upstanding hypodermic needle 14 contacting with its end the inner wall of the hollow bullet. A compression ring 16 or the like rests upon the needle plate 15.

After the cartridge has been fired and the bullet l1 impinges on the target the upper part of the bullet starts to be compressed as shown in FIG. 2 and the needle 14 penetrates through the wall of the hollow bulletportion lla into the target. Upon further compression the ring 16 compresses the sack l3 and forces the anesthetic therefrom through the needle 14 into the target.

The upper portion 110 of the bullet can be made of an elastic material which will extend towards its original shape after having reached the position shown in FIG. 3 and thus automatically withdraw the emptied bullet 11 from the target.

In the embodiment illustrated in FIGS. 4 and 5 the plate 15 of the needle 14 is rigidly seated within the outer part 11a of the hollow bullet body. In the inner part of the said bullet body is a piston 17 and between the same and the needle plate 15 an anesthetic medium. While the bullet impinges upon the target and the needle 14 penetrates the wall of the compressed outer portion 11a of the bullet as shown in FIG. 5 the pistonlike member 17 moves forward and presses the anesthetic medium through needle 14 into the target.

ln a third embodiment shown in FIGS. 6 to 8 the lower part of the bullet 11 is solid and only its upper part is hollow and compressible. This part houses the hypodermic needle 14 with its perforated baseplate 15 which is rigidly seated in the bullet 11 above its solid lower portion. The anesthetic medium is filled into the hollow bullet body 11a said plate 15. When the bullet impinges on the target and the needle 14 penetrates its wall to enter the target as shown in FIG. 7 anesthetic is pressed through the perforated needle plate 15 shown in top view in FIG. 8 into the space below the same and from there through needle 14 into the target.

While three specific embodiments of my invention have been shown and described in detail to illustrate the application of the principles of my invention, it will be well understood that the same may be otherwise embodied without departing from such principles.

What I claim as my invention is: 1. In a hypodermic projectile including a shell housing, a

detonator and a bullet inserted therein, the improvement comprising in combination: a bullet having an outer hollow portion made of a ductile material to be deformed upon reaching a target; an upstanding hypodermic needle having a baseplate positioned within said bullet and separating the deformable portion from the remaining portion of said bullet, said needle penetrating the top of said deformable portion of said bullet upon impact of same with a target; a hypodermic medium within said remaining portion of said bullet; and means causing the hypodermic medium to flow through the needle into the target upon impact.

2. In a hypodermic projectile according to claim 1 wherein the means causing hypodermic medium to flow through the needle into the target comprise: a compressible sack containing the hypodermic medium in the remaining portion of said bullet, said baseplate resting upon said sack; and a compression member positioned within said deformable portion of said bullet which acts in conjunction with said baseplate to compress the sack upon said bullet impacting said target to force hypodermic medium thereinto.

3. In a hypodermic projectile according to claim 1 wherein the means causing hypodermic medium to flow through the needle into the target comprise: a baseplate firmly seated in the hollow bullet; and a pistonlike member below said plate to be forwardly propelled after impact of the bullet and to press hypodermic medium placed in front thereof through the needle into the target.

4. la a hypodermic projectile according to claim 1 wherein the means causing hypodermic medium to flow through the needle into the target comprise: a perforated baseplate firmly seated in the hollow bullet; hypodermic medium above said baseplate; and a reverse space below the faceplate so that the compressed outer part of the bullet forces hypodermic medium downwardly through the baseplate into the reverse space and from there upwardly through the needle into the target.
